Oprah Winfrey's exclusive no-holds-barred interview with Lance Armstrong, "Oprah and Lance Armstrong: The Worldwide Exclusive," has expanded to air as a two-night event on OWN: Oprah Winfrey Network. The special episode of "Oprah's Next Chapter" will air Thursday, January 17 from 9-10:30 p.m. ET/PT (as previously announced) and Friday, January 18 at 9 p.m. ET/PT. The interview will be simultaneously streamed LIVE worldwide both nights on Oprah.com.

Armstrong will address the alleged doping scandal, years of accusations of cheating and charges of lying about the use of performance-enhancing drugs throughout his storied cycling career. Winfrey speaks with Armstrong in the only interview since the seven-time Tour de France winner was stripped of his titles and dropped from millions of dollars in endorsement deals after the U.S. Anti-Doping Agency released an extensive report accusing the renowned cyclist of doping throughout his career.

Armstrong was given a Lifetime ban on competing professionally. Late last year, Armstrong resigned as chairman of the foundation he created, Livestrong, which has raised hundreds of millions of dollars in the fight against cancer.
